A without any excuse fires a loaded cannon into a crowd of persons and kills one of them. He had no premeditated design to kill B. What offence, if any, is committed by A?

The Governing Provision: Clause 4 of Section 300 IPC / Clause (d) of Section 101 BNS

The law does not define murder only by reference to premeditated intention. It also captures those acts of extreme recklessness and callousness — where the actor may not have wanted to kill any particular person — but where the knowledge of the near-certain probability of death is so clear that the law treats it as equivalent to intentional killing.

Clause 4 of Section 300 IPC, reproduced as Clause (d) of Section 101 BNS, provides that culpable homicide is murder —

"if the person committing the act by which the death is caused, knows that it is so imminently dangerous that it must, in all probability, cause death, or such bodily injury as is likely to cause death, and commits such act without any excuse for incurring the risk of causing death or such injury as aforesaid."

The Illustration appended to this clause states expressly: "A, without any excuse, fires a loaded cannon into a crowd of persons and kills one of them. A is guilty of murder, although he may not have had a premeditated design to kill any particular individual."

The problem before us is that very illustration, brought to life. A is guilty of murder under Section 300 IPC read with Section 302 IPC, and equivalently under Section 101 BNS read with Section 103 BNS, punishable with death or imprisonment for life along with fine.

Why the Absence of Premeditation Does Not Help A

The defence that immediately springs to mind is that A had no premeditated design to kill B specifically. He did not aim at B. He had no particular grudge against B. He may not even have cared who died — he simply fired into the crowd. Many students, and indeed many untutored minds, instinctively believe that the absence of specific targeting must reduce the gravity of the offence. The law firmly rejects this instinct under Clause 4.

The entire philosophical foundation of this clause rests on the recognition that there is a species of culpability which is not intention in the traditional sense, but which is equivalent to intention in its moral weight. The person who fires a loaded cannon into a crowd knows — with a certainty approaching absolute — that human lives are in the path of destruction. The knowledge is not of the death of B in particular; it is of the death of some person drawn from the crowd as a matter of near certainty. The Supreme Court in Willie (William) Staney v. State of Madhya Pradesh (AIR 1956 SC 116) clarified that Clause 4 is specially designed for acts directed not at any particular individual, but against persons generally — acts where "there is no intention to cause death of any particular person, but the act is done with such callousness towards the result and the risk taken is such that it may be stated that the person knows that the act is so imminently dangerous that it must in all probability cause death."

A man who fires a loaded cannon into a crowd is not inadvertent. He is not momentarily distracted. He is in full possession of his faculties and full knowledge of what a cannon does. The act is one of supreme indifference to human life — what the law characterises as extreme depravity of mind — and the Code treats such indifference as the moral equivalent of deliberate killing.

The Critical Words: "Must, in All Probability" and "Without Any Excuse"

Two elements of Clause 4 deserve particular attention, for it is their combined presence that lifts the offence from culpable homicide to murder.

First, the degree of probability required is not mere likelihood. Clause (c) of Section 299 IPC (which defines culpable homicide) uses the words "likely to cause death" — meaning a probable result, where the chances may be fifty-fifty or somewhat higher. Clause 4 of Section 300 elevates this to "must, in all probability, cause death" — meaning the result is virtually certain in the ordinary course of events. The Supreme Court in State of Andhra Pradesh v. R. Punnayya (AIR 1977 SC 45) authoritatively explained this gradation, holding that the distinction between Clause (c) of Section 299 and Clause 4 of Section 300 "relates to the degree of probability of death" and that Clause 4 applies "where the knowledge of the offender as to the probability of death approximates to a practical certainty." A loaded cannon fired into a crowd is not merely likely to kill someone; it is virtually certain to do so. No reasonable mind could suggest otherwise.

Second, the clause requires that the act be committed "without any excuse for incurring the risk." This is the element that distinguishes A's case from the case of a surgeon performing a high-risk operation, or a soldier firing under lawful orders, or a person acting in private defence. None of those situations are excuseless — each has a legally recognised justification for incurring the risk. A, by contrast, has no excuse whatsoever. He fired a loaded cannon into a public crowd for no purpose that the law can recognise as legitimate. This excuselessness is the final nail in the coffin of any defence.

The contrast with Emperor v. Mt. Dhirajia (AIR 1940 Allahabad 486) is instructive. In that case, a woman fleeing a brutal husband jumped into a well in a panic, resulting in her infant's death. The Allahabad High Court held that although she had the knowledge that jumping into a well was likely to cause death, she had an excuse — the panic and fear of her husband. She therefore could not be convicted of murder under Clause 4, and was instead convicted of culpable homicide not amounting to murder under Section 304 Part II. The contrast with A's case is stark. A has no excuse — no fear, no compulsion, no lawful authority. The act is pure, excuseless recklessness amounting to the gravest depravity.

The Concept of "Imminently Dangerous Act" — Its Distinct Character

It is worth pausing to appreciate what makes Clause 4 distinctive in the architecture of Section 300 IPC / Section 101 BNS. The first three clauses of Section 300 all rest on intention — intention to cause death, intention to cause a known fatal injury, or intention to inflict an injury sufficient in the ordinary course of nature to cause death. Clause 4 is the only clause that rests entirely on knowledge, dispensing with intention altogether. It is designed, as the Supreme Court recognised in Willie Staney, for "the rarest of rare cases" where the accused puts in jeopardy the lives of many persons by a single act of supreme recklessness — firing a cannon into a crowd, poisoning a public well, opening the grid of a bridge just as a passenger train approaches.

In Santosh Shankar Pawar v. State of Maharashtra (AIR 2015 SC 3789), the Supreme Court convicted an accused under Clause 4 (fourthly of Section 300 IPC) for pouring kerosene on his wife and setting her ablaze. The Court held that even assuming the accused had no intention to cause death, the act of pouring a flammable substance and setting a person on fire is "so imminently dangerous that in all probability such an act would cause death." Any person of average intelligence, said the Court, would know this. If that is the standard for a domestic act in a moment of passion, the case of a person firing a loaded cannon into a crowd admits of even less doubt.

In State of Haryana v. Krishan (June 9, 2017, Supreme Court), persons who deliberately adulterated country liquor with methyl alcohol and sold it, resulting in 36 deaths and 44 persons losing their eyesight, were convicted of murder under Clause 4. The Court held that those who mix a lethal substance into a drink intended for public consumption know that their act is so imminently dangerous that death must in all probability result. A's act of firing a cannon is no different in principle — indeed, it is more direct and more obviously deadly.

The Irrelevance of the Victim's Identity: A Fires Into a Crowd, B Dies

An important subsidiary question is whether the fact that B — and not some other named person — died has any bearing on A's liability. The answer is that it has none.

Section 301 IPC (corresponding to Section 102 BNS) codifies the English doctrine of transfer of malice and provides that if a person by doing an act with the intention or knowledge required to constitute culpable homicide, causes death of a person whose death he neither intended nor knew himself likely to cause, the culpable homicide is of the same description as it would have been if that person had died. The operative mental state travels with the act and attaches to whichever death results. A fired into a crowd knowing the act would in all probability kill someone. B was that someone. The species of homicide is determined by A's knowledge, not by B's particular identity.

The Punishment: Section 302 IPC / Section 103 BNS

Since A has committed murder under Section 300 IPC / Section 101 BNS, he is liable to be punished under Section 302 IPC / Section 103 BNS, which prescribes death or imprisonment for life along with fine. The absence of premeditation does not reduce the offence below murder in this case, because none of the five Exceptions to Section 300 IPC are attracted. A was not acting under grave and sudden provocation; he was not exceeding a right of private defence; he was not a public servant; he was not acting in a sudden fight; and the victim certainly gave no consent. Every escape route from the category of murder is firmly closed.

The Larger Principle: Knowledge as a Substitute for Intention

This problem teaches one of the most important distinctions in the entire law of homicide. Indian criminal law recognises that knowledge of a virtually certain consequence is, for the purposes of liability, the equivalent of intention. A general rule of criminal law — that every sane person is presumed to intend the natural and probable consequences of their acts — finds its highest expression in Clause 4. When A fires a loaded cannon into a crowd, the natural and probable consequence is not merely possible death — it is virtually certain death. The law accordingly treats A as though he intended the death that resulted, and the offence is murder in its fullest sense.

As it was once put in the context of the mental element in culpable homicide: "If A fires a loaded pistol in a crowded road, it leads at once to the inference that his intention was to cause death, though he might not have desired to kill anyone." The cannon in our problem is only a more powerful and more indiscriminate expression of the same depravity. A is guilty of murder, punishable under Section 302 IPC / Section 103 BNS.
